Sasuke is one of the last remaining members of the Uchiha clan, one of the most powerful groups of ninjas in Hidden Leaf Village. Because of his advanced bloodline, Sasuke inherited the potential for many powerful ninja techniques. Probably one of his most effective techniques is the Sharingan in his eyes which allows him to predict and copy an enemy's strategy, giving him the ability to counter attack and to strengthen the copied ability. His superb ninja skills and intelligence in battle made him a top-ranking student in his class and pretty much all the girls adore him for his serious and "cool" nature(though Sasuke couldn't care less about popularity.)

Although Sasuke puts on the facade of being stoic, unemotional, and indifferent, he harbors a deep yearning of revenge for a horrible incident that happened to him long ago...when his older brother Itachi murdered his parents and the entire Uchiha clan simply because he wanted to test the limits of his Sharingan power. It's not certain why Itachi let only Sasuke survive, but perhaps it's because he feels that Sasuke may eventually develop the power and hatred to be a worthy opponent. But whatever his reason, Sasuke refuses to give up or die under any circumstances until he's able to carry out his revenge on Itachi. At first he wasn't very happy being placed in the same group as Naruto and Sakura. Sakura's major crush on him and Naruto's loud-mouthed personality irritated him, but after the trio faced many difficult and life-threatening battles together, Sasuke finally warmed up to them a little bit. Although he and Naruto never get along very well, they eventually develop a kind of respect for each other, especially when they both risked their lives to save each other during one of their earliest and toughest battles with the powerful ninjas Zabuza and Haku. Naruto and Sasuke will always be rivals, but while Naruto wants to prove his worth to other people, Sasuke's mysterious goal of vengeance seems to be about proving something to himself.
